Apostoliki Diakonia is the official publishing house of the Orthodox Christian Church of Greece. Since 1936 it has published hundreds of books on christian theology and tradition, Orthodox spirituality, biblical studies and fiction for children.

"Praxis", a publishing house specialized in textbooks for German as a foreign language, was founded in 1985 in Athens from his current owner and leader Spiros Koukidis, German teacher and author with work experience of more than 30 years in the field. In the forst years of its existence the publishing house was focused on the distinctive features of the Greek market for German as a foreign language (concentration on the various exams and need for general supplementary materials).
The break of the century brought a change of direction to the company. A series of textbooks with clear orientation towards the international market have been published, mainly from language B1 upwards, ensuring their quality by first trying them out in the classroom before launching them. Praxis Publications grew in this way into a medium-sized (for Greek standards), heavily export-oriented publisher, well-known for its learner-friendly textbooks of highest quality, which sometimes serve highly specialized market segments.

Agra Publications were founded in 1979. They have published 800 titles of Greek and world literature, art, architecture, drama, crime fiction, children's books, essays and ancient Greek and Byzantine texts.
